Custom Made 520 Conversion Kit with Vortex Sprockets and RK Racing Chain! By converting to a 520 setup you will not only replace your existing setup with the best looking chain and sprocket set on the market... You will reduce weight (over 1.5 lbs), heat, & friction while increasing horsepower (to the rear wheel). This RK GXW XW-Ring Racing Chain reduces friction (drive chain resistance) by over 50% when compared to a standard O-ring chain.

The Vortex front sprocket is machined from the highest quality steel. Case hardened and precision cut with less than. The Vortex rear sprocket is computer designed and machined from the highest quality 7075 aerospace aluminum. Saber tooth grooved for self-cleaning and electrically coated for a brighter finish. 99-09 SV650S SV 650S (15/44-factory)!

A 120 link chain is a few links longer than your factory chain and essential when adding teeth to the rear sprocket or with an extended swingarm. Intended for street or race use but not pactical for drag racing applications because of wear. The increase in power of 520 systems is found in acceleration from slow to low speeds and not dead starts. (8800 lbs of tensile strength)!
